Cataplana de Marisco
A cataplana is a hinged copper clamshell pan, and the seafood stew named after it is one of those dishes where the cookware does the work. You build a base of onions, peppers, sliced chouriço, smoked paprika, tomato and white wine in the bottom of the cataplana, then layer clams, mussels, prawns and chunks of firm white fish on top, clamp the lid shut, and steam it all for less than ten minutes. The lid lifts at the table to release a cloud of paprika-and-wine-scented steam, which is the entire point of the dish. If you do not have a cataplana, any wide pan with a tight lid does the same job. Coriander and lemon at the end, crusty bread for the broth, and vinho verde for everything else.
